Massive Distal Forelimb Fibromyxoma in a Free-Ranging American Alligator (Alligator mississippiensis)

Abstract An adult male Alligator mississippiensis (American Alligator) with a large growth on the right forelimb was harvested from the wild by a nuisance-control trapper in Louisiana. The mass was determined histologically to be a fibromyxoma. To our knowledge, this neoplasm has not previously been described in American Alligators.
